If you are a command-line person, GoogleCL is a quick way to get acquainted with the Google+ API. Try this:
- Install GoogleCL using the instructions here.
- Run the following command line: google plus activities list me public
You will need to authenticate with your browser the first time through, but after that, things will work without the browser. Then you can do something like running the output through "say":
google plus activities list me public --fields items/object/content --maxResults 1 | say
to have your computer read you your Google+ posts!
This is a silly example, but it highlights the power of the Google APIs Discovery Service. Upon launch, the Google+ API was available in GoogleCL, the Google APIs Explorer, and the .NET, GWT, Java, Objective-C, PHP, Python, Ruby and Go API clients! And as the Google+ API grows, these tools will almost instantly grow right along with it. Pretty neat, huh? You can learn more about how this all works here: http://code.google.com/apis/discovery/
